Abstract
A portable magnetic resonance system includes a permanent magnet, a nuclear magnetic resonance probe, and control electronics. The control electronics are configured to transmit to the probe a magnetic resonance excitation signal having an excitation frequency f, receive from the probe a magnetic resonance measurement signal, detect in the magnetic resonance measurement signal a magnetic resonance frequency f0, and automatically adjust the excitation frequency f until the difference between the excitation frequency and the magnetic resonance frequency is approximately equal to a target offset.
